Not sure but I bought a 2003 Chevy Tracker brand new v6 4x4 when I was stationed in alaska (only because I have 2 small children lol)...I believe it has mazda engine it it. Not the fastest thing (very far from), but reliable as hell..nearing 90k miles and never had a single problem w/ it besides changing the pads on the front brakes and some new tires...Still runs like a top. Oil change every 3k is all it takes
